TO CLIFFORD MANU- WATER common.

Application The present invention relates to improvements in temperature-controlled apparatus the circulating systems of motors, and represents more particularlyimprovement in the type disclosed in the application of Clifford, Serial No. 150,368, filed November 23, 1926.

In the type of construction disclosed in this application, a skeleton cage supports a thermostat and valve assembly directly within the circulating system. he

' designed to accurately control the openlng temperature of the valve and afiord a minimum of interference wit the flow of water when the valve is in fu open position. p

The object of the present invention is to improve and somewhat reorgan ze the con- 'struction describedin order to increase the strength and rigidity and the resistance to vibration inevitably present with the operation of a motor vehicle.

With this and other objects in view, the various features of the invention consist in certain novel features of construction, comb nations and arrangements of parts hereinafter described and claimed, the advantages of which will be obvious to those skilled in J "the art from the following description. In the accompanying drawings illustrating the preferred form of the invention,

Fig. 1 represents an elevation partly in section of the thermostatically-controlled valve assembly; an

Fig. 2 is a top plan view of the assembly shown in Fig. 1. 1 The construction shown inthe illustrated embodiment of the invention comprises essentially two U-shaped members 10 and 12, each provided with longitudinal legs'or sup-' ports 14, formingthe sides 0 the cage an extending lengthwise thereof. The two U shaped members are retained in assemble relation by a partition disk 16, through which the legs 14 pass adjacent the upper and a supporting disk 18 rigidly secured to the lower ends of the members. A. collapsible and expansible bellows 19 is connected to the disk 18 at the lower end, as indicated, and at its upper end is provide with a stud 20 to which is' directly con- The valve seats upon 16 to close a; valve opening .24

erature at which the valve opens is controlled by the operation of the bellows 19 in the usual manner, the valve being adjusted with relation to the stem 20 to accurately determine the opening point. When properly adjusted, the valve is locked in position upon the stem by form ng elongated indentations 26 at opposite sides, which are 0 sufficient length to encompass at least two threads and by malforming these threads prevent any movement of the valve with relation to the stem.

The longitudinal supporting members 14 are rigidly locked to the partition disk 16 and the end supporting and eifi-c'ent manner.

For this purpose each of the longitudinal members is provided at I throughout the length with recesses or notches 28 and 30, respectively, which are adapted to respectively receive and embrace a portion of the partition disk and supporting disk. In. addition eac of the disks is provided with openings 3 and 34, which approximately tudinal members 14 and permit the latter to be freely passed therethrough. In assembllng. the partition disk 16 is firstmoved upthe longitudinal members until forced toward one another until the notches embrace and sides of the openings 3 Tbs locking of the longitudinal members to the partition disk is conveniently accomplished by a locking ring 36 having an opening somewhat smaller than the outer circle of the openings 32 and designed to retain the longitudinal members in the position shown in Fig. 1. When in position the locking ring not only rigidly maintains the longitudina members and partition disk in the assembled position indicated dition substantially seals the openings 32 against any flow of water therethrough.

the lower ends the longitudinal members are locked in the openings 3 in somewhat the same manner, in this case the members being retained in the position shown, through the employment of solder 38, which serves to closethe openings and preserve the. assembled relationship.

What is claimed is: 4 1. Temperature-controlled apparatus comprising a thermostat, a valve connected with movable thereby, a partition member provided with a valve opening and a plurality of support openings, longitudinal supports extending through the corresponding openings in the partition member and having shoulders designed to engage with the partition member on lateral movement of the longitudinal members with relation to the openings, and means for rigidly locking the longitudinal members and partition members in position with the shoulders engaging the partition member.

Temperaturescontrolled apparatus comprising a thermostat, a valve connected with the thermostat and adapted to be, moved thereby, a partition member having a series of openings extending therethrough, longitudinal supports extending through the openings and having notches adapted to engage and embrace the sides of the opening of the longitudinal supports with relation thereto, and means for locking the longitudinal supports and partition member in position with the notches engaging the sides of the opening.

3. Temperature-controlled apparatus comprising a thermostat, a valve connected therewith and adapted to be moved thereby,

a partition member provided with a valve opening andia series of support openings, a
